RAI LWAY- SIGNAL.

SPECIFICATION forming part of Letters Patent l \To. 291,545, datedJanuary 8, 1884.

A l cation filed AugnstQl, 1883. (No model.)

Be it known that I, ABRAHAM B. SNYDER, a citizen of the. United States,residing at Louisville, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in BailwaySignals; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon, in which- Figurel is a top view. Fig. 2 is aside view,

line H H of Fig. 1.

The present invention has relation to railway-signals designed to beused at street-crossings; and its nature consists in the several partsand combination of parts hereinafter set forth.

Similar letters of reference indicate corresponding parts in thedrawings.

Arepresents the spring, which is of the form shown in Figs. 1 and 2, andshould be made of the best spring-steel, its normal form being as shownin Fig. 2, and is located at the side of part will extend a shortdistance above the top of the rail, as shown in Fig. 2. One end of thisspring is firmly held to the cross-tie by means of screws or spikes,said end having a large flat surfaceto prevent said spring from movinglaterally. The opposite end is firmly attached to the rod B by rivets orbolts. The opposite end of the rod B is attached to the bottom or lowerend of the signal-arm O by a rivet or bolt, and is attached so as toform a hinge or joint. The rod B is held in proper position by means ofthe boards D and blocks E, said boards having a longitudinal recess.which fits over a corresponding recess in the blocks E, as shownin Fig.3. C are fulcrumed to the segment F, as shown in Fig. 1, and are soarranged that they will be easily operated by means of the spring A androd 13 as a train passes over said spring. The signal-arms 0 should beheld a short distance apart, which is done by means of a washer placedbetween said arms, as shown in Fig. 3, so that the movements of the arms0 will not interfere with each other. The top or upper ends of thesignal-arms O are provided with the signals G,'and may be of any desiredform, and should be painted with some bright color, and one a differentcolor from the other. It will be seen that as a train of cars passesover the spring A said spring will be pressed down to a level with thetop of the railway-rail, thereby forcing the end of said spring forwardand causing the rod Bto move the signal G, and as soon as a wheel haspassed The signal-arms said spring it will assume its normal position,

thereby causing the signal to be waved by the wheels of a passing train,one of these springs being placed on each side of the street and at asufficient distance from the street to signal the approach of a train intime to prevent any accident.

. Having now fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The boards D, provided with longitudinal recess, and the blocks E,having recess, in combination with the rod B and spring A, substantiallyas and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein presence of two witnesses.
